An industrial explosion from a gas piping project kills four workers in North Carolina. A boiler-related explosion at a nursing home in Michigan kills five. An explosion from a power plant gas piping project in Connecticut also kills five. These tragic stories may have made national headlines, but every year hundreds more go overlooked.
EZ-Purge Automatic Drain Valve The EZ-Purge is used to automatically open a motorized ball valve or electric solenoid valve for a set amount of time from 1 to 60 seconds. Activation occurs each time power is applied to the interval timer.

Clearly if a boiler is operating over a wide temperature/pressure range, such as when boilers are on night set-back, or even a boiler with a wide burner control band, then compensation is required, since conductivity is the controlling factor. The benefits of automatic TDS control. The labour-saving advantages of automation.
The continuous desalting valve is used to empty an adjustable quantity of water from the steam boiler, removing: Organic matter and mineral salts in solution. (Calcium, magnesium, sodium, potassium, iron, bicarbonate ions, chlorides, sulphates, nitrates, …etc.). Solid materials in suspension.
The purge of airflow removes gaseous combustibles in a furnace and replaces it with air. As mentioned in our previous post about the NFPA86, any residue can lead to a fire or explosion, so this is an important process. Each part of a furnace, from the burner up to the stack, must be purged. The stack, however, does not have to be purged.
Aug 19, 2014· The air purge valve (APV) (Nos. 5 and 6 oil only) remains de-energized. At the same time, the program relay signals the modulating damper motor (MDM) to open the air damper. The damper begins to open and drives to its full open or high-fire position. Opening the damper motor allows a flow of purging air through the boiler prior to the ignition cycle.
Industrial boiler systems can cope with much higher pressures than pressure cookers. These boilers are welded from thick steel plates that are up to 35 mm thick, making pressures of 30 bar and more possible. A stable, robust design is also essential – if a boiler of this type were

Jun 26, 2018· 1. The Pre-purge Process equipment requires at least four air changes of the fire box before an ignition source can be introduced. Multiple burner boilers have a number of issues that must be considered to calculate the proper purge time. Multiple burner boilers must have purge times that are a minimum of five minutes.
